Purpose To use strain rate imaging (SRI) to compare the abdominal aortic wall elasticity between patients with type 2 diabetes mellitus and controls. Methods We measured the abdominal aorta intima‐media thickness (IMT) with B‐mode echography, and the anterior and posterior wall displacement (d), strain, and strain rate (SR) with SRI, in 90 patients with type 2 diabetes mellitus and 30 control subjects (group A). The patients were classified into group B (normal IMT), group C (thickened IMT), and group D (one single atheroma plaque). Results d, strain, and SR were significantly lower in group B, C, and D than in group A ( p < .05). Systolic, early‐diastolic, and late‐diastolic SR were lower in patients with diabetes (especially in group D) than in controls. There were significant differences in systolic SR, early‐diastolic SR, and late‐diastolic SR between group A and group B ( p < .05). Conclusions SRI is a noninvasive method that can demonstrate a loss in aorta wall elasticity in patients with diabetes with normal IMT. © 2014 Wiley Periodicals, Inc.
